Other claims from this paper (8)
- Observation Pb causes oxidative stress in plant roots and produces free radicals.
- Mechanism Free radicals produced by Pb act on membrane lipids, causing lipid peroxidation and cell membrane damage in plants.
- Observation Pb primarily moves into the apoplast of plants.
- Mechanism Higher Pb concentrations may interrupt the casparian strips of the endodermis, allowing Pb ions to enter the vascular tissue of plants.
- Observation The number of mitochondria increases in Pb-stressed plants, attributed to a higher demand for ATP generation.
- Observation Pb exposure induces structural anomalies in plant roots.
- Observation Root surfaces of Pb-exposed plants show withered cells and dense growth of root hairs.
- Observation Pb exposure affects growth and physiology of plants.
